Windsor-Essex sees a big jump in COVID-19 with 17 new cases

The Windsor-Essex County Health Unit reported 17 new cases of COVID-19 Tuesday a sharp increase compared to the low number of daily newcases it has reported overthe past week.

WECHU officials say contact tracing has revealed that:

• Nine of the new cases are from close contact in the same household as a previously-confirmed case.
• Oneof the new cases arefrom close contact with a person in a differenthousehold; another previously-confirmed case.The two households are not believed to be connected.
• Two of the newcases are from close contact witha case outside the public health unit.
• Three of the new cases were possibly acquired in the community, but the source is unknown.

The final two cases are still being investigated.

"The WECHU continues to investigate the links between the cases. There is no community cluster for us to investigate at the moment as the cases are tied to their respective households," the health unit said in an emailed statement to CBC News.

It's not clear why Windsor-Essexafter having just one new case yesterday and a lower number of new cases compared to many other areas of the province over the past week has seen such a jump.

Public health declined to comment today but said it will take questions during Wednesday's daily virtual COVID-19 briefing.

The bump in new cases comesjust overtwo weeks afterThanksgiving, and while the Ministry of Health has pointed to Thanksgiving as one reason behind a spike in cases over the weekend,theWECHU has not made that direct connection. CBC News asked WECHU medical officer of health Dr. Wajid Ahmed in Friday's briefingif he was still waiting for an increase in cases Thanksgiving long weekend. Ahmed repliedthat symptoms for people infected over Thanksgiving would have most likely shown up four to five days after exposure.

The health unit, like many others in Ontario and across Canada, encouraged people to celebrate the holiday only with those that they live with.

Windsor-Essex has now had 2,812 confirmed cases of COVID-19, 44 of which are active, and 76 deaths.

Two workplaces continue to experience outbreaksaconstruction workplace in Lakeshore, and afood and beverage workplacein Kingsville. No long-term care homes in Windsor are currently experiencing outbreaks.
